Big pharma, insurance, and lawyers have been dictating medical practice for many years now. Doctors are just the middle-men and there's absolutely no free market competition.

Modern medicine and government mandated insurance (insurance of all kinds) are the biggest scams going these days... It's absolutely money driven!
